What is the minimum percentage of admixture used in design mix?

Question

Accepted Answer

The minimum percentage of admixture used in design mix varies depending on the type of admixture and the desired properties of the concrete.

The percentage of admixture used in design mix can range from 0.1% to 5%.
Admixtures are added to concrete to improve its workability, strength, durability, and other properties.
Common types of admixtures include water reducers, air-entraining agents, accelerators, retarders, and superplasticizers.
The amount of admixture used should be determined based on the specific requirements of the project and the properties desired for the concrete.
The use of admixtures can also affect the setting time, curing time, and cost of the concrete.
